Foods such as milk, meat, and sliced fruit need to be kept under 40 degrees to be considered safe. To create a safer lunch, freeze items like juice boxes, water, and milk, as well as soft cheeses, chicken salad, and other perishable items. Packing them in an insulated lunch box (or bag), including two ice packs, and ensuring that the bag is sealed tight will also help. When doing your back-to-school shopping, consider adding some of these 10 safer lunch box items to your list — your lil one's stomach will thank you!
